The status of the Taiwanese endemic Aleuritopteris agetae remains unresolved. This taxon is said to differ from A. krameri s.s. in its milky yellow (vs. white) farina and stipe scales that are sometimes slightly bicolorous. Ralf Knapp (pers. comm.), the author of a recent authoritative guide to the pteridophytes of Taiwan, Ferns and Fern Allies of Taiwan (2011), has stated that where the two taxa grow together they are readily distinguishable in the field. However, based on examination of herbarium material collected in Taiwan, the present authors could not consistently discern two discrete morphological entities. Some of the specimens from mainland China also appear to have milky-colored farina. The situation requires further study.
